UNHTT STATES ATENT MOLD.

Application filed March 9, 1926. Serial No. 93,541.

This invention relates to certain improvements in molds and it is primarily an ob ject of the invention to provide a mold especially designed and adapted for use in the production of hunting knives, kitchen knives and the like and particularly for use informing the handles.

It is also an object of the invention to provide a mold of this kind provided with means whereby the blade is properly supported with respect to the handle during the molding oi the handle together with means whereby said handle may be formed with an internal chamber or pocket for the reception of matches and the like.

Another object of the invention is to provide a device of this kind whereby a brassguard or the like may be provided at the blade end of the handle and whereby such guard is properly applied to the handle during the molding operation.

Furthermore, it is an object of the invention to provide a mold of: this kind constructed in a manner whereby gas and air bubbles may readily escape during the molding operation or more particularly during the time the metal is being poured.

The invention consists in the details of construction and in the combination and arrangement of the several parts of my improved mold whereby certain important advantages are attained and the device rendered simpler less expensive and otherwise more convenient and advantageous for use, as will be hereinafter more fully set forth.

The novel features of my invention will hereinafter be definitely claimed.

In order that my invention may be the better understood, I will now proceed to describe the same with reference to the accompanying drawings, wherein Figure 1 is a view in top plan illustrating a mold constructed in accordance with an embodiment of my invention with a knife blade and ginird in applied position;

Figure 2 is a view in top plan of the structure as illustrated in Figure 1 with a patlern section or member removed;

Figure 3 is a sectional viewtaken sub stantially on the line 3-3 of Figure 1 with the blade in edge elevation;

Figure i is a sectional. view taken substantially on the line 4 -4 of Figure 1;

Figure 5 is a view in elevation of a completed knife resulting from the use of the mold as herein disclosed;

Figure 6 is a view in top plan with a portion broken away of a mold constructed in accordance with a further embodiment of my invention.

As disclosed in the accompanying drawings, M denotes the main member of my improved mold, an end portion of which being raised, as at 1, to provide the pattern section for the handle and over which is adapted to be disposed the second pattern section or plate 2 for the handle. This plate 2 adjacent to one end is provided with openings 3 which readily receive the pins 4 extending outwardly from the raised portion or pattern section 1 when the plate or pattern section 2 is in applied position. The outer face of the pattern section or plate 2 is provided thereacross with an outstanding rib or flange 5 upon which bears an end portion of a spring 6, the opposite end portion of said spring being bolted or otherwise connected, as at 7, to a lateral extension plate 8 carried by the main or body member M and extending to one side or the raised portion 1. This spring 6 exerts sufficient pressure upon the pattern section or plate 2 to maintain the same in applied position with respect to the raised portion or pattern section 1.

The section or plate 2 also has extending laterally therebeyond a handle member 9 whereby the same may be readily and conveniently manipulated by the operator.

Connected to an end portion of the body member M by the transversely spaced arms 10 is a blade supporting plate 11 coplanar with the body member M. This plate 11 is provided with the outstanding and transversely spaced bolts 12 which are received within the open slots 14 produced in the extremities of the shims 15. The shims 15 are arranged in overlying relation and of a suificient number to properly position the blade B of a knife to which the handle is to be applied and particularly to position said blade B to assure the tang 16 thereof properly extending between the applied pattern sections or plates 1 and 2 and more especially to bring said tang 16 to the center of the pattern formed in said sections or plates.

The blade B is held to the shims 15 by a holding cleat 17 provided'in one end portion with a longitudinally disposed open slot 18 to receive one of the bolts 12. while adjacent to its opposite end said cleat 17 is provided with a transversely directed open slot 19 to receive the second bolt 12. The application of the cleat 17 may be readily accomplished by first engaging one of the bolts in the open slot 18 and then swinging the cleat 17 in a direction to receive the second bolt 12 within the trans versely disposed slot 19. Jitter the cleat 17 has been properly applied with respect to the blade B and associated shims 15, the

cleat 17 is firmly held in applied position through the medium of the nuts 20 threaded upon the bolts 12 and having contact with the outer face of the cleat 17.

The end portion of the cleat 17 provided with the slot 19 is provided with an extension 21 alfiord'ing a handle or hand grasp whereby the cleat 17 may be readily manipulated by the operator.

It is 'to be understood that the blade B is applied to the mold before its edges have beentinished or, in other words, in its rough condition, the dressing of the blade and the handle ll bolted thereon being finished after the molding operation.

The pattern formed by the assembled mold sections or plates is initially open at opposite ends and the tang 16 is inserted through a guard G ot'brass or other desired material, said guard abutting an adjacent end of the assembled pattern sections or plates. The guard G, as particularly illustre-ted in Figure 3-, is of a type having the spaced flanges 22 disposed toward the handle end of the knife. Before the pouring operation, the open ends between'said flanges 22 are closed by asbestos stop-out putty or the like.

lCie handle H is preferably formed of aluminum and as the molten metal is poured into the opposite end of the pattern it heats the tang 16, annealing it and making it very tough and also properly enters between the flanges of the guard G assuring such guard being effectively maintained in desired applied position. The guard G in a iinished'lrnite adds to the beauty and attractiveness thereot and the metal which extends within the groove of the guard between the flanges assures said guard G 7 being etlectively held against wabbling.

The finished knife, as illustrated in Figure 5, is of a hunting type and in the molding of the handle H l lind it of particular advantage to provide the outer portion of said handle H with a pocket or recess 23 indicated by broken lines in Figure 5 and the outer end of which being normally closed by a screw plug 24: or the like. Before the handle H is molded, I insert within the outer end of the pattern the suitably designed core 250f molders wax or as otherwise preferredcarried by the cylindrical stem 26. This stem 26 constitutes a continuation of an elongated member 27 which is adapted to be clamped to the main body M in a manner'to assure the proper positioning of the core 25 within the pattern.

As herein disclosed, the body member M at a point spaced from the outer handle end of the pattern is provided with the upstanding bolts 28 with which is interlocked, through the medium of the longitudinally disposed open slots 29, the plate 30 mounted on said body member M and extending transversely thereof. The shims 3-1, when necessary, are inserted in desired hum er between the member 27 and the plate 30 to assure the desired positioning of the core25 and the stem 26, after which said core is effectively held in said position by the cleat 32. This cleat 32 is provided in one end with a longitudinally disposed open slot 33 to receive one of the bolts 28 and adjacent its opposite end with a transversely disposed open slot 34 to receive the second bolt 28. This cleat- 32 is clamped to the member 27 by the nuts 35 threaded upon the bolts 28 and contacting with the outer face of the cleat 32. The end portion of the cleat 32 provided with the transversely disposed slot 34 is continued to provide the handle or hand grasp 36 whereby the cleat 32 may be manipulated in substantially the same manner hereinbefore set forth with respect to the cleat 17.

It is to be noted that initially the inserted tang l6 and core 35 are substantially surrounded by an open space. This is of particular importance as when the metal is poured within the mold gas and air bubbles will readily escape.

In the en'll'iodim-ent of my invention just described, the metal is poured in the tore end of the i'nold but in the embodiment of my invention as illustrated in Figure 6. the outer handle end portion of the mold or pattern is closed and the metal poured in the blade end of the mold, such portion or the pattern being enlarged. as at 37, and the formation of the rough of a guard integral with the handle proper. In this embodiment of my invention it is not required that holding means he provided for a core and for this reason the spring 6 is attached directly to an end portion ot the body member M and thus materially simplifying the structure of the mold.

From the foregoing description it is thought to be obvious that a mold constructed in accordance with my invention is particularly well adapted for use by reason of the convenience and facility with which it may be assembled and operated, and it will also be obvious that my invention is susceptible of some change and modification without departing from the principles and spirit thereof and for this reason I do not wish to be understood as limiting myself to the precise arrangement and formation of the several parts herein shown in carrying out my invention in practice except as hereinafter claimed.

I claim 1. A mold of the class described, comprising a base member provided with a pattern section, a pattern plate adapted to overlie the pattern section of the base member, an outstanding rib on said pattern plate, a lateral extension on the base member. a spring carried by the lateral extension and bearing against the rib to hold the pattern plate in applied position, and means for holding a core within the end portion of the resultant pattern.

2. A mold for forming a handle upon a knife blade, comprising, in combination, a base member provided with a pattern section, a pattern plate coacting with the pattern section, an end of the resultant pattern being open, a blade supporting plate at one end of the base member, spaced bolts on said blade supporting plate, a plurality of shims arranged in superimposed relation having open end slots for receiving said bolts, a holding cleat having a transverse open slot in one edge for receiving one of said bolts, and a longitudinal open slot in one end for receiving the other bolt to securely clamp said knife. lade upon the shims.

In testimony whereof I hereunto affix my signature.

JOHN HERBERT WILLIAMS.
